Just for the sake of completeness, I made a small change to the Operation Eyestrain logo, which is visible on the first post but not yet in the project. It now includes a Star Wars element (it had none before, and I can't believe I never thought of it until now). Anyway, now it fits a little better with the others, even though it's always going to be a bit of an inside joke with limited popular appeal.
EDIT: Thought of a slogan too, but it doesn't go with the image: "We stare because we care"
